Application med September 26, 1910. Serial No. 583,792.

Beit known that LNOAH GORNFIELD, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Vehicle-Wheel, of which the following is a full, clear, and exact description.

My invention relates to Vehicle wheels, my more particular purpose being to provide a wheel with springs suitabl arranged for taking up the play of the ax e, and performing generally the oiiice of a pneumatic tire.

More particularly stated, l provide a wheel having a non-revoluble central portion of comparatively large size, and connect the axle centrally with its portion and arrange around said portion a member revoluble relatively to the same and free to turn` thereupon; the axle and parts secured rigidly thereupon being connected with said central member by aid of suitable springs, which'allcw a play of the axle relatively to the outer portions of the wheel.

Reference is to be had to the accompanying drawings forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the views, and in whichof a disk.'

Figure 1 is a section on the line 1-1 of Fig. 2 looking in the direction of the arrow;

Fig. 2 is a section on the line 2--2 of Fig. 1

looking in the direction of the arrow; Fig. 3 is an elevation showing the inner faceof the wheel; and Fig.' 4 is a section on the line 4-4 of Fig. 1 looking in the direction of the arrow.

- A disk 5 comprises practically the outer face of the wheel and is provided with a pocket 6, having the general outer appearance of 4a hub. The inner face 7 of the wheel is made in halves and has generally the form At 8 is a rim which is sandwiched between the outer face 5 and the inner face 7.

At 9 are bolts for connecting the rim 8 with the inner and outer faces of the wheel. A tire 10 ts against the rim 8 and engages the adjacent edges of the inner and outer faces. Disposed within the rim -8 are two annular members 11, the surfaces 'of which are suitably formed to constitute ball races. nside of these annular members 11 are two other members 12 also formed into ball races. Between the annularmembers 11-12 are two rows of balls 13.

At 14 is a rim support having the general form indicated in passages 15 wherebyits weight is lessened.

YThe rim support 14 is provided internally wlth the large Iaperture 16 having generally n arnular form as will be understood' from At 17 is a block through whichextends a square portion 18 of the axle which is shown Patented Dec. 'A7, 1915. t

Fig. 1 and provided with .slots 22, disposed oppositely to each other.

The block 17 carries two guide blades 23 extending in opposite directions into the l.slots 22. Each blade 23 is encircled by a spiral 4spring 24, and presses against the block 17 and also against a plate 25, the

latter beingv loose relatively to the Irim sup-- pgrt 14. his rim support is further provided with slots 26, and tine block 17 is pro` vided with pins 27, which extend through compression springs 28 and into the slots 26. rlhe pins 27 have no appreciable play 1n therslots 26, except in the general direction of the planeof the wheel and iny the general direction of the length off the pins.

: At 29-30-31 are suspension springs which are connected with the block 17 and also with the upper portion of the rim support 14. Below kthe block 17 isa compression `spring 31", and extending through the sameis a guide pin 31h, which reaches into a slot 31. v

At 32 are compressionsprings, and extending .through the same are gulde ypins 33.

At 34 are tensile springs which reach from the block 17 to the lower inner surface of the rim support 14. The tensile springs 34 terminate 1n end portions of wire which are secured directly tothe block 17, the oppof -site ends of the springs being connected with the support 14. These tensile springs v34 are not so closely wound as to unduly restrict movements of the block 17. The guide pins 33 extend into slots 35 which are Some;

l what similar to the slots 26 and allow the 37 being corrugated, as indicated in Fig. 4,- play relatively to the axle, and as the ring A `the ball bearings.

guide pins a limited play in two directions, their play being practically limited, however, in the direction crossing the general plane of the wheel.

Encircling the axle 19 and revoluble 'relatively to thesame, is a ring 36. Concentric to this ring 1s an annular sprocket 38. .A diaphragm 37 lmade of corrugated leather is connected with the annular sprocket 38 and with the ring 36, so as to form therebetween a dust proof connection. Thefdiaphragm allows the annular sprocket 38 more or less turns freely upon the non-revoluble axle and fits the same practically dust proof', the en-v tire outer portion of the wheel turns.

The operation' of my device is as follows: The parts beingy assembled asabove described, and the vehicle being drawn over the ground, the outer portion of the wheel, that is the tire 10 and rim 8, together with the inner andouter faces, turn as a unit upon the block 17 has considerable play vertically, and a slight play forward'andbackwardthat is in thev general direction in which the vehicle is traveling-#but little or no play' in a direction crossing the general plane ofy the wheel.v` The guide blades 23 lit neatly into the slots 22 so as to prohibit any appreciable play in alateral direction, while allowing theblock 17 considerable move ment up anddown, and a slight' movement forward or backward, reckoned according to the general direction in which the wheel i i is traveling. The wheel rim support 14 has a` resilient relation to the block 17 and yet A serves as a non-revoluble member upon 'which the outer portions of the wheel are free to turn.

I do;v not limit myselfto the precise'com- I struction above described, neither do I limit myself to the employment of any special materials in the construction of this *wheel7 rate with my claim.

While this is the case,`

two subscribing witnesses.

1,1es,soe

the scope of my invention being commensu- The combination of a non-rotary recta'n` gular block; a non-rotary open-centered ring member surrounding said block in a plane coincident therewith; a rotary ring member, embodying a wheel tire and felly surroundlng said nonrotary ring member in spaced relatlon thereto; a plurality of' rolling members interposed between .said ring members'to form a bearing in' said rotary,

ring' member and to maintain the spaced relation vof said members; and a plurality of springs interposed between said nonrotary ring member and said block, said springs being disposed at the four sides of said block andl said springs being graduated with reference to thedisposition, theload supporting springs being disposed below y saidl block, shock-absorbing ysprings being disposed above. said block and centering' vsprings being disposedbefore and behind said block, said springs being balanced to normally maintain the said block concentric with said ring members under 'predetermined load conditions imposed on said block.

In testimony whereof I have signed my name to this specication in the presence of NOAH ooRNrIELD, Witnesses:
